A
One in which the nucleus decays spontaneously, giving off particles and energy
2
Q
What is the functional property of a sulfhydryl group
A
Two sulfhydryl groups can bond covalently forming a “cross link” that helps stabilise protein structure

-phospholipids(glycerol + 2 fatty acids)
-steroids( a type of lipid characterised by a carbon skeleton which had four fused rings), eg cholesterol
